glow worm problem

[skaman]

hi every one im new to this forum and need help.

i have a problem with our glow worm micron boiler.
when its raining it wont start up it just cuts straight out and trips the electric. if i place a blow heater in front of it for about 20 minutes or so then switch it back on it starts fine. ive had the cover of and carnt see any damp or wet. ive also looked down the outside flue when its raining to see if theres any rain getting in. nothing its a dry as a bone.

any ideas would be appreciated.

thanks.

As its doing it only when raining,water must be getting in somehow,and its unlikely to be a boiler leak.A thorough check needs to be made of the flue installation and that it is sealed correctly on the outside.Your PCB is vulnerable and not cheap to fix.Get an RGI to check it over,as he will remove the case assy and check inside for problems.
